The novel air-flow impacting (AFI) synthesis technology for mechanochemical synthesis of MOFs (ZIF-67) was first reported. AFI was an improvement of the traditional mechanochemical synthesis method. The results indicated that ZIF-67 was successfully synthesized after 30 min at a rate of 60 kg h−1. The as-prepared ZIF-67 was characterized by Fourier transform infrared spectroscopy (FT-IR), powder x-ray diffraction (P-XRD), thermogravimetric analysis (DTA/TG), scanning electron microscope (SEM), transmission electron microscope (TEM), and single-crystal x-ray diffraction. The kinetic analysis of the reaction mechanism was carried out by detecting the P-XRD patterns of the products with different reaction times. The synthesis belonged to the one-dimensional diffusion-controlled model.
